Cutting and Folding Paper and other Fab;

rics, of which the following is a specification.

In a machine embodying the present invention in its entirety there areemployed in connection with cutters for cutting sheets from a web inmotion a folding mechanism consisting of two rotary cylinders furnishedrespectively, with cooperating folding blades and v grippers.

The invention consists in certain n,ew combinations in which saidmechanism and the cutters constitute elements, as hereinafter describedwith reference to the accompany- 2o ing drawings, and the novelty ofwhich is specifically pointed out in the concluding claims.

In the drawings, Figure l is a side elevation of all the parts of acutting and folding machine necessary to illustrate my invention and oftwo packers employed in connection with said invention; Fig. 2, avertical section corresponding with Fig. 1 and taken parallel therewith;Fig. 3, a plan of one of the said packers; Fig. 4, a horizontal sectiontaken centrally through the folding mechanism on a scale larger thanthat of Figs. 1, 2, 3; Fig. 5, a vertical section on the line 5 5 ofFig. 4; Fig. 6, a vertical section in the line 6 ii of Fig. 4; Fig. 7, avertical section on the line 7 7 5 of Fig. 4. Figs. 4:, 5, 6, 7 are on acorresponding scale, larger than that of Figs. 1, 2, 3.

A designates the bed-plate, on which is erected the side framing B, onwhich are the bearings a for the shafts b of the rotary-cut- 4o tercarriers and the bearings c for the journals d of the rotaryfolding-cylinders, one of which is designated as a whole by the letter Cand the other by the letter C. Each of these cylinders, which are of thesame size,

5 is furnished with a folding-blade e and with grippers f g, the saidfolding-blade and grippers on each cylinder being diametrically oppositeeach other and the two cylinders being geared together by spur-gears D Dof the same size in such manner that the foldingblade on each cylindermay in the rotation of the cylinders enter between and cooperate withthe grippers of the other cylinder. The rotary-cutter carriers, theshafts of which are geared together by spur-gears E E' of equal size,are represented as furnished with two sets of cutters, the blades h ofwhich are set diametrically opposite each other for cutting from a webto during each rotation two sheets to be folded at the middle of theirlength by each revolution of the cylinders C C, the edges of saidcutters being at proper distances from the axes of their carrier-shaftsb to cut the sheets of the proper length. The cylinders have acircumference equal to twice the length of the cut sheets, and they andthe cutters are driven at the same speed. This driving may be effectedby any suitable means. I have represented it as effected through ahorizontal shaft F, (see Fig. 2,) 7-0 which itself derives motionthrough bevelgears G H from the shaft I of a printing-machine, thecutting and folding machinery in the example represented being supposedto be the adjuncts of such a machine. The said shaft F carries abevel-gear J, which gears with and drives a bevel-gear K on a horizontalshaft L, which carries also a spur-gear M, (see Fig. 1,) which gearswith the spur-gear D on the shaft of the cylinder C, and so drives thecylinders C C. The said shaft L also carries another spur-gear O, whichgears with a spur-gear P, turning on a fixed stud 7: on the framing.This gear P gears with and drives a spur-gear Q, which turns on a fixedstudj on the framing and which engages with and drives a spur-gear R onone of .the shafts b, and s0 drives the cutters.

The cutter-carriers and cutters which I prefer to use in carrying outthis invention are 0 those which are the subject of United States PatentNo. 391,949. The folding-grippers f g are such as constitute part of thesubject-matter of my United States Patent No. 629,928;butthefolding-bladese,thoughserv- 5 ing the same purpose as thefolding-blade which constitutes part of the subject-matter of thatpatent, are differently applied to the cylinders in that instead ofbeing pivoted thereinto to provide for their turning to and fro betweena radial and tangential position, as in that patent, they are fastenedto bars 10, which are rigidly fixed within the cylinders. For thepurpose of conveniently applying the said bars 10, the blades, and thegrippers to the cylinders the latter are constructed as represented inFigs. 4, 5, and 7, as will now be described with reference to thosefigures. This description being given for one cylinder, will beunderstood as applying to both. The body of the cylinder is composed ofa shell 11, having integral heads 12 and having diametrically oppositeopenings 13 14, (see Figs. 5 and 7,) one for the folding-blade and theother for the grippers. The journals d are represented as made separateand provided with flanges 15, through which (see Fig. 4) they are boltedto the cylinder-heads 12 by bolts 16. The bar has its ends bent at rightangles to form eyes 17, which receive the inner ends of the journals (1and which for the purpose of keeping the blade in the proper positionwith reference to the circumference of the cylinder are secured to thecylinderheads 12 by screw-bolts 18. The blade 6 is secured to itscarrying-bar 10 by a clampingbar 19 and clamping-screws 20. For thepurpose of permitting to the blade a slight flexibility to accommodateitself to the grippers and facilitate its withdrawal from between thelatter after the tucking of the fold between them there is formed alongthe blade, on one side thereof, as shown best in Fig. 5, a groove 21,and the inner face of the clamping-bar is chamfercd or beveled outward.

The grippersfg of each cylinder are composed substantiallyas shown in myPatent No. 629,928, hereinbefore referred to, of a jaw f, forming partof a cranked bar having at its ends journals 22, which work in bearingsin brackets 23, affixed to the cylinder-heads 12, and a jaw or fingerscarried by a shaft 24, which is journaled into the cranked portions ofsaid bar, and the said bar is furnished at one end with an arm 26,carrying a roller 27, which runs in the groove 28 of one of twostationary cams S S, which surround the cylinder-journals and aresecured to the framing B. Fig. 6 is a face View of one-of these cams andof the arm 26 and roller 27 and shows one of the journals 22 of the barfin section. By the rotation of the cylinder and the consequent travel ofits roller 27 in the groove of its respective cam the grippers arecaused to turn at the proper times between positions radial to thecylinder for receiving the fold-line of the sheet and a positiontangential to the cylinder for delivering thefolded sheet, as describedin my United States Patent No. 629,928, part of the subject-matter ofwhich is afolding-cylinder similar to those 0 O in that it carriessimilar folding-grippers which operate in combination with afolding-blade on another cylinder and which are turned by a cam likethose S S. For the purpose of closing the grippers a spring 29 isapplied, as described in my said Patent No. 629,928, between a lug 30 onan arm 31, which projects, as shown in Figs. 4., 5, and 7, from one ofthe cranked portions 25 of the gripper-bar f, and an arm 32, which isprovided on the shaft 24 of the jaw g. It is not, however, intended thatthe jaws and 9 shall ever come quite close together, and to prevent thatthere is provided on one of the cranked portions 25 of the barf a stop34 for arresting the arm 32 of the shaft 24 of the jaw g, as shown inFig. 7, in such position as to leave a just sufficient opening between fand g to permit the fold-line of a sheet to be tucked between themtightly by the folding-blade 6. Thus it will be understood that thegrippers do not have any positive opening movement to receive the tuck.They are only opened positively to liberate the folded sheet. Thislatter operation is produced by a stationary cam T, (see Figs. 4., 5,and 7,) located within the cylinder and against which at the properperiod in each revolution of the cylinder there runs an arm 35 on theshaft 24 of the jaw g. This cam is carried by a short shaft 36, whichpasses through one of the cylinder-journals d. For the purpose ofadjusting the said cam T to liberate the folded sheet at exactly theproper time and securing said adjustment the shaft 36 has an attachmentoutside of the cylinder. This attachment is represented in Fig. 1 asconsisting of an arm U, fastened on the end of the shaft 36, whichprojects through the end of the cylinder-journal outside of the framingB, the said arm having in it an arc-formed slot 37, through which passesa screw 38, which is screwed into the framing and by which the said armmay be clamped to the framing when the proper adjustment of the cam hasbeen made by placing said arm at the proper height.

In order that the grippersfg of each of the cylinders O 0 shall properlycooperate with the folding-blade c of the other of said cylinders, thecams S S are offset in opposite directions from the axes of theirrespective cylinders, as will be understood by reference to Fig. 4, andto preventinterference with each other of said cams and the engagementsof the grippers with them said cams are arranged one at one end of itsrespective cylinder and the other at the opposite end of its respectivecylinder, as shown in the same figure. The axes of the two cylinders C Cand the axes of the cutter-shafts b b are arranged in two horizontal orparallel planes the distance between which is somewhat greater than thelength of the sheets to be cut and folded in order that the sheets maybecut from the web before they are taken at the middle of their lengthbetween the folding blades and grippers of the two cylinders.

For the purpose of presenting the cut sheets positively to the twocylinders there are provided two sets of carrying-tapes 70, running at aspeed corresponding with the surface speed of the cylinders. Each ofthese sets of tapes runs over one of two rollers Z, located between thecutter-carriers and cylinders and both run together between said rollersand between the two cylinders. Each also runs partly around one of thecylinders and between it and rollers 711, located below it on two shafts40, arranged in suitable fixed bearings, and also runs around rollers n0 20, carried by standards V V,thence, as may be traced by reference toFigs. 2, 5, and 7, back to and over the rollers Z, between the cuttersand cylinders. There need be but two tapes k in each set to take thesheets at or near their margins. tapes to and from the cylinders withoutinterfering with or being interfered with by the folding-blades andgrippers, recesses 61 are provided for such passage, as shown in Fig. 4,in the folding-blade bars 10 and in the gripper-jaw f. Thetapes havetheir motion given to them between their respective cylinders and saidrollers m, said rollers also having a positive motion given to them at asurface'speed corresponding with that of the cylinders through aspur-gear W (see Figs. 2, 4, 5, and 7) on one of the journals of thecylinder G, the said gear W gearing with gears m one on each of the twoshafts 40 of the rollers m belonging to the cylinder 0' and also gearingthrough an idler-gear 'r with a gear 'm* on one of the shafts 40 of therollers m belonging to the cylinder 0. The latter gear 001* is alsogeared through an idler-gear s with the other gear m*, belonging to thesame cylinder (J. All of the shafts 40 except that one to the extremeleft in Fig. 7are representedas having bearings in the side frames 13,and that one as having its bearings in brackets 13*, which are securedto the side frames and in which are the bearings for the shaft L,hereinbefore described.- The rollers Z run loosely on two fixed shafts41, which are supported in the side framing.

The two sets of tapes 7c constitute not only an endless feeding-carrierfor presenting the cut sheets to the folding-cylinders, but constitutemembers of delivery carriers, which carry away the folded sheets eitherto packers XX or to any other receptacle or place of deposit. As afeeding-carrier the two sets simply cooperate with each other betweenthe rollers Z, there taking the sheets between them. As a member of oneof two endless delivery-carriers each set cooperates with one of twosets of tapes t, which constitutes its fellow member. The said tapes irun between thev cylinders and the rollers m outside of the tapes 7i andalso run over and around the pulleys n, before mentioned, and they gettheir motion with the tapes 70, between the cylinders and the rollers m.In Fig. 2 the rollers p are represented as tightening-rollers for thetapes It, and tightening-rollers q are shown for the tapes 23. Under oneset of the tape-rollers Z and opposite the corresponding set there aretape-rollers it, carried by arms To permit the passage of said 42 on oneof the shafts 41. The two sets of rollers Z a on one side of the tapesIt assist each other in cooperation with the roller Zon the oppositeside to give the tapes a sufficient bite upon the sheet. The stationarytaperoller shafts 41 are represented as carrying stationaryguide-fingers 6O, between which the terminal portion of the web beforethe sheet is cut from it is conducted between the two tapes 70. Whenpackers are employed in connection with this folding machinery, they maybe of any known or suitable kind, one for each folding-cylinder. Toillustrate such employment, those represented in Figs. 1, 2, and 3,which are of a well-known kind, serve as well as any others. These havebeen herei'n previously mentioned and each designated as a whole by oneof the letters X X and will now be described in only snificient detailto illustrate their cooperation with the deliverycarriers. A descriptionof one of them will, except as to the provision for driving them fromthe shaft L, apply to both. Each consists of a bedplate M, on which aretwo parallel troughs v, communicating with opposite ends of asemicircular passage, which is formed by upright walls 20* w* and inwhich work packing-fingers 43, carried by the two ,95

arms 44 of an upright shaft m, (see Fig. 3,) which has a reciprocatingrotary motion to the extent of half a revolution, the said arms 44 beingunder the bed-plate and the fin gers 43 projecting upward through curvedslots 45 in the bed-plate. In the Walls w* 10* of the semicircularpassage are upright grooved guides 55 for the reception of the edges ofthe folded sheets which are dropped into the said passage from thedelivery-carriers, the packers being suitably arranged relatively totherollers n 0 of the delivery-carriers for such reception. By thereciprocating rotary motion of the shaft m the sheets dropped into thepassage 10* 10* are packed one at a time into one and the other of thetroughs v alternately. The movement of the shaft 00 is obtained from abevel-toothed sector 46 on a horizontal rock-shaft 47, arranged underthe bed-plate,the said sector gearing with a bevelwheel 56 on the shaft00. The rock-shafts 47 for operating the two packers derive their motionfrom two crank-wrists 48 on a disk 49, carried by a shaft 50, whichworks in bearings in a standard V and which carries a spur gear 51,through which it receives rotary motion from a spur-gear 52 on the shaftL, hereinbefore described. One of the crank-wrists The construction andthe separate operations of the several parts of the machinery having nowbeen sufficiently described, it remains to briefly describe theconsecutive operations of cutting the sheets from the web and foldingand delivering them. The web cam passing through one of the journals ofsaid cylinder, and an attachment to said shaft outside of the cylinderfor turning said cam for taking from each alternately the sheets foldedby its own grippers, and packers one for each cylinder for separatelypacking the folded products from the two cylinders, substantially asherein described.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of two witnesses, this 25th day of June,
